[o all whom t may concern.'

Be it known that I, HERMAN Gr. LinnEN- THAI., a subject of the Emperorof Germany, having declared my intention of becoming a citizen of theUnited States, residing in Philadelphia, Pennsylvania, have inventedcert-ain Improvements in Printing Mechanism, of which the following is aspecifica tion.

My invention relates to printing machines, and consists primarily ofmechanism which is particularly serviceable when used as an` auxiliaryattachment for machines of the type known as offieeor duplicating"machines for printing letters, circulars, etc.. which have theappearance of having been separately Written on a typewriting machine.Vhen used for this latter purpose, my invention is especially adaptedfor printing electrot-ypes of signatures, signing clauses, letter heads,etc.

In the above mentioned types of office machines, bthe body of the letteror circular to be printed is set up by selecting and. sliding individualtype-letters from a niagazine into grooves of a plate or rotatablecylinder and printed through the medium of an As it is desirable to havethe signing clause or signature inade by an electrotype and printed in adifferent color ink from the body of the letter, such signatures aiidsigning clauses were heretofore made by a separate. operation. In otherprinted, the type constituting the body of the letter had to be removedfrom the rotatable cylinder and replaced in the magazine; then anelectrot-ype of the signature was inserted-in the rotatable cylinder,after which a different. color ink-ribboii was brought into operationand the letter again passed through the machine to receive theimpression of the electrotylie. This not only required a lossolfdtime-in inserting the electrotype and passing the letters. cir.,thro-ugh the machine twice, but oflcn caused the same to become marredand unerenly printed.

The chief object'of my invention is to construct' printing mechanism ofthe above type that. will make itpossible to print` in one operation.yletters having a signature or other matter produced in a color which isdifferent from that ofthe body of the letter. Another object is that theconstruction of my invention will be durable, easy to adjust and whichmay be easily attached-to and cooperate with another printingmachinewhen it is .so desired. l

These and other objects and advantages@- I attain in the followingmanner, reference being had to the accompanying drawings, in which: v

Referring to the drawings.tlie main frame l of a rotary printing machineforms a rotary support for a shaft 2 liaving a typedrum 3 and a handle 4fixed thereto. A platen roll 5 is rotatably mounted on the frame 1adjacent the type drum S. and it is between the latter and the platenroll 5 that the blank sheets of paper are inserted. 'The foregoingelements may be of any known type and do not form a part of myinvention.

Side brackets or frames and 7 are secured to the main frame 1 and formthe support for two rot-ary shafts 8 and t) and a shaft loehavingeccentric trunnions 10. Intel-meshing gear wheels 11 and 12 are keyed tothe shafts 8.and t), respectively. 12 is loosely mounted .on a lsleeve6a; the latter forming a bushing for and concentric with one of thetrunnions 10". The other of the ti'unnions 10. extends into anecrentli'r recess in a VIArviutff. .\n elliptical 11( gear slotv13a isformed in the gear 13 and forms .a' driving means more fully referred tohere v and 18 fixed thereto. A gear 19, intermeshingwi'th gear 16, isrotatably mounted on a 21. Another gear 23, made integral `with the gear19 in the present instance, Vis also journaled on the stud-shaft 21.'Two st-ud shafts 24 and 25 extending from the bracketI 6 form a bearingfortwo gearsA 26 and 27; the' gea-r 26 being in mesh with the gears '12and 13; and the gear 27 being in mesh with the gears 13 A ina-in drivinggear wheel 28 in the present instance is fixed on the shaft. 2 andmeshes with the gear-23. A f Y v `The sleeve 15 forms a guide for alever 29 by passing through a slot 30 inthe said lever@ l In likemanner, a rod 31 attached to the bracket 6, acts as a guide for thelever 29 by passing through a. slot 32 therein, (Fig. 9). A shaft havingeccentricl trunnions 34 is journaled in the brackets 6 and 7.'

.A pendentor carriage 351is journaled on the shaft 33 and is grooved at36 for the reception of type or electrotype 37. An anti-friction wheel38 is journaled on a pin 39 extending from the carriage 35 and 'adaptedto be engaged by the cam 17A to rock or' swing the said carriage in amanner more fnllyreferred to hereinafter. l A chain 40 has one endYattached to a ltrunnion 34 and the other end attached to an arm 41extending -fron the lever 29. The chain 40 is always kept taut by theaction of a. torsion spring 42 which has one end attached and has theother en d frolled onthe spool 47, as clearly shown o'p Figs-3 a A.d 6.

A double-arm liever? 4 9 is pivo ed on the carriage 35 at a tensionspring 51 has one end connectef to the frame 6 andi the otherend to onelijm of the lever 49% In like manner, a tension springt, 52 is at-itached to the other anni of thef lever 49g and to the carriage The .sa dspring'` 51 is stronger than the spring 52 s` that the the `spring 52. Adouble pawl 55 is oted Von the shank of a screw 56; the said screwhaving its inner end engaging a tapped bore of av sleeve 57 adapted toav slot 58 in an extension 59'of -the carriage 35.

A shifting lever 60 is provided with a slot 61 througlrwhichpasses theshank of the' screw 56, and a tension spring 62 is centrally connectedto the pawl 55 and to the shifting lever 60. A second sleeve 63 is alsomovable within the slot 58 and a pin 64 passes through the sleeve 63 andis screwed into a locking plate G5. A portion of t-he screw 56alsopasses-through a bore in the' plate 65 so that the said late 65cannot -possibly have arocking motion with respec't to the carriage A35,but can slide in a direc-v tion as prescribed by the slot 58. The plateY A 65 isprovided with a pin 66 which coperates with V-shaped lslot 67'formed in-l gageinent with its. respective ratchet wheel 53 -or 54. Apin 69 passes through the lever 49 and a plate70, and is screwed intothe sleeve 57, (Fig. 7). The-pin 64 valso passes through the plate 70sothatthe latter acts as4 .a slide operable against the outside surfaceof the extension 59. v

A rubber coated 'roller .71 is loosely mounted on the shaft 10, and hasa pin 71 projecting frombne end and engaging Tthe slot 13 in the gearwheel. A13. A hand Wheel 73 is keyed on the trunnion 10a adjacent thesleeve. 72, and pin 74, threaded at .the free end, projects from theframe 6 and extends through the slot 72. A lever 75 is mounted on thethreaded portion of thepin 74, and when turned,'tends lto lock or unlockthe hand Wheel. A tension spring 76 has oneend attached to a pin 77extending from the frame 7 and the other-end attached to a pin 78carried by the carriage 35;- the function of the spring 76 bein to movethe carriage 35 in the direction o the arrow, Fig. 5, to print. Theshaft 8 is'adjust-ably mounted in eccentric bearings 79 in the frames 6and 7, and is provided with wheels 80'and 81 which contact with wheels82 and 83 on the shaft 9 and form a conveying means for the Qother endattached to a pivotedv latch leveji 4 I88. The carriage 35 carries a lug89 which spring 51 would normally tend to,` ttenuatei 1vis adapted tostrike the lever 88; the latter tending to tighten the spring 86 and'act as a bufi'er -for the carriage 3 5 so as to prevent theanti-friction roller 38 from pounding on the cam 17.

The 'hand wheel 73 is slotted at 'looj l A Y In order that theoperationwill be easily understood, it will be assumed that the machine is atpresent equipped for writing and signing a letter; the mainlcylinder 3being set up to print the body of the letter' and the carriage 35carrying an electrotype to print the signature.

The operation is as follows: The blank paper is inserted at and betweenthe cylinder 3 and the platen roller 5. The handle 4 is then turned inthe direction of the arrow, Fig. 1, and the paper is thereby fed towardthe top of the rubber coated roller 71. In passing between the cylinder3 and the platen roller` 5, the body d of the letter is printed thereon.D being rotated, the gear 28 imparts motion to the chain of gears 23, 19and 16, and 23, 27, 13, 26, 12 and 11. The gear 16, being keyed to thesleeve 15 rotates the cams 17 and 18. The cam 18 acts against theanti-friction roller 43 to lower the lever 29, (see Fig. 9), and therebypull the chain 40. In so doing, the eccentric trunnions 34 are turned(in the direction indicated by an arrow, Fig. 11) against the action ofthe torsion spring 42, so as to lower the shaft 33 and necessarily thecarriage 35. lVhen the carriage 35 has been lowered the prescribeddistance, the anti-friction roller 38 is opposite a steep portion of thecam 17 so that the spring 76 will contract and swing the carriage 35 sothat the electrotype 37 will contact with the paper to print thesignature. The roller 71 is driven 'through the medium of the pin 71aextending` into the slot 13a and, as the gear 13 is timed to give theroller 71 the same surface speed as the cylinder 3, feeds the finishedletter toward the conveying wheels or rollers 80-83 from where they areejected. After the electrotype has finished printing, (Fig. 12) the cam18 passes away from the anti-friction roller 43, and the torsion spring42 turns the trunnions 34 in the direction of the arrow, Fig. 13, and byso doing, winds the chain 40 thereon and raises the shaft 33 andcarriage 35. As the chain 4() is wound on the trunnion 34, the lever 29will be raised t0 the position shown in Fig. 13. After the electrotypehas been raised, the cam 17 engages the anti-friction roller 38 andswings it into the position shown in Fig. 11, and the operation is againre eated to print the next letter. When it is esired to change theposition of the elee'trotype impression with respect to the body portionof the letter, the clamp band 20 is loosened and the hand wheel 20turned until the gear 16 moves ont ot' mesh with the gear 19.

The cams 17 and 18 can then be shittedto' any desired position, afterwhich by again turning the hand wheel 2" *he gear 16'can be brought intomesh wit the gear 19. Thus it willy be noticed that v`h my invention, asignature or other impression can As the cylinder 3 is' be made on anydesired position of a sheet of paper, and that the camscan readily beadjusted to change the time and position ot the impression. For example,if the carriage 35 is operating to print a signature at the extremebottom of the letter and it is desired to have the signature printed inanother position with respect to the body of the letter, it is onlynecessary 'to turn the 1 hand wheel 2Oa to unmesh the gears 16 and 19and turn the cams 17 and 18 to a position l that will allow the carriage35 to move in contact with the roller 71 at the proper time to make theimpression in the desired place. l The roller 71 may be bodily adjustedto ward or from the carriage 35 by loosening the lever 75 and turningthe hand wheel 73 to vary the character of the impression. Or, if it isdesired to change the alinement of the roller 71 with respect to thecarriage, it is only necessary to turn the eccentric nut 7'f.

The movement of the carriage 35 effects the feeding ot the inked ribbon48 over the face of the electrotype 37 in'the following manner:Considering that the shifting level' 6() has been manually lowered tothe posi tion shown in Fig. 6, the forward movement of the carriage,(see arrow, Fig. 6l allows the spring 52 to slide the pawl 55 over oneof the teeth of the ratchet wheel 54 without turning the latter. On thereturn l movement of the carriage 35, the latter will move faster thanand away from the pawl 55, and, as the spool 47 having the ratchet wheel54 thereon is directly connected to the carriage 35, the ratchet wheel54 and spool 47 will be rotated thereby. causing the inked ribbon 48 tobe wound on the spool 47 to bring a fresh portion of the said inkedribbon .into contact with the electrotype 37. 'hen the spool 46 isnearly empty, the shifting lever 60 can be raised until the uf)- pertongue of the pawl 55 meshes with the teeth of the ratchet wheel 53, andthe spool 46 is rotated to rewind the inked ribbon thereon by themovement of the carriage 35 in exactly the same manner as abovedescribed relative to the. spool 47. The lever 6() is locked in itsraised position owing to the fact that the lower end oi the V-shapedslot- 67 will be pressed against the pin (it). The spring 51 will act asa safety means to prevent the ends of the inked ribbon from being tornaway from their respective spools in the operator fails to notice wheneither spool becomes nearly empty: the spring 51 being just strongenough fo resist. without stretching. thtl friction necessar)Y to rotatethe spools under ordinary conditions. but will stretch it any additionalstrength of the sp1-ing 51, the.pa\vl 5T will move in the same path withthe carriage 35 and the' spring 5l will stretch.

In the form of my invention shown in Fig.v 14, I have dispensed with thechain and substituted an arm 907 hivingan antifriction roller 01. at oneend.Y-attached to a split clamp' hand on one ot the trunnions A cam '02on the sleeve 13 operates against the anti-friction roller 91 to movethe arm and thereby turn the trunnion to lower the carriage 515. I mayuse the torsion spring 42 to operate against the action of the cam 90for raising the carriage 35, or I can use a tension spring 91. In thelatter case, the saidlcnsion spring)r 04 has one end attached to aprojection 95 on the frame and the other end attached to, a lever 96extending from one of the tronnions 34. Also in Fig. 14, I have shownmeans for adjusting the carriage 35 to a1 low for variable printingimpressions. In' this latter case, the trunnion 30 is milled overaportion of its surface to form worm teeth 97 and the split band 98placed thereon. The split band may be clamped to the said trunnion bymeans of a screw 09. An extension 100 of the band 08 forms the housingtor' a rotatable worm 101 which meshes with the teeth 9T and has a'slot103 formed therein. When it is desired to raise or lower the shaft 55:;and carriage 35 independently of the regular operation of the machine,the-screw 09 is loosened and the'worm 101 turned by a screw driver o1`'other means. For most classes of Work, I prefer to use the'construction of the printu ing elements shown in Fig. 11 as the samepermits a very accurate adjustment.

In Figs. 15 and 16, I have shown a construction Where the carriageadjustment means can be used, in case I desire to use the chainformation. In cases where it is desired to attain a very accurateadjustment of the cams to properly position the electrotype impressionwith respect to the body ofthe letter, I have shown (Fig. 1S) aconstruction where the cams can be adjusted without throwing the gears10 and 19 out ot' mesh.`

The form shown in Fig. 10 shows means for supplying ink direct to theeloctrotype by means of a series of rollers 101..` 103 and 106,journaled in a'tray 107. The hottom ot the tray `107 is shaped so asiloform drip receptacles 108 and 1 00 for the rollers 10.7 and 106respectively .and an inl( `fountain 110 into which the roller 104extends.` The ,tray 107 has bars 111 connected thereto and adapted toslide within slideways 112 iu the frames 6 and 7 and to be locked by setscrews 111, A gear 1.13 meshes with the gear 1.6 and a gear 114 loose onthe roller 105. The gear 114 meshes with a gear 115 fixed to the roller106. Another gear 114 Vis keyed to the roller 10J and meshes with gears110 and 11T .fixed to) the rollers 104 and 100 rcspectively. Adjustinginca for the roller 107i comprise a set screw 118 and a (xnnprcssionspring' 111:1 which are housed within the tray 10T and adapted to pressagainst the axle of the roller 10i. and to move the latter toward oraway from the roller 10? when the set screw 11S is turned. Motion isimparted p through the gears Milf-11S to the roller 104 which conveysthe ink to the roller lt'which in turn carrics the ink to the roller100. The electrotype during the forward swing ot the Carriage contactswith the roller 100 and receives ink therefrom. The roller 106 alsotends to feed the carriage atthe same time as the latter is being inked,thus insuring an equal distribution of ink over the electrotype.

In Fiff.' '30. I have shinvn another form of supplyinrY ink directly tothe electrotype and consistsmt two "rotatably mounted rollers 120 and1:21. .The roller 120 covered with an ahsorbcm .natcrial which is keptsaturated with ink. ln operation. the surlace of the roller lift is.icpt cow-rml with ink b v tiring in contact with the roller 190 andthecarriace movesy the clectrotype in contact with the roller 121 andreceives a coatingF of -inlr therefrom. d ip pan 122 is placed lnrneaththe rollers 120 and 1:21 so as to catch any inl( that' may drop therefrom.

lVhile I ha vc described the carriage 35 as carrying an electrotype of asignature in the operationvof my invention. it will be under stood thatany kind of type can he placed within the grooves oi' the carriage toprint letter heads or othc;` desirable n'laterial. Also. two or morecarriages can be arranged in tandem form to print different imprcssionsin one passage of the paper through vthc machine.

lly using.r the carriage 21.3 in the manner describetLI am ahle toattain cleabcnt even impressions on long and short paper, and thc typecarrying area of the bottom of the 'ari-lage may he of any size.

It will he further nnderstfimd that while 'l' have illustrated and.described my invention in combination with a rotary printing machine myinvention can be used with other forms of machines or independently ofanother machine.
